Be sure to read both documents before using the lens.This lens is designed for Sony α mount cameras (models equipped with APS-C sized image sensor). You cannot use on 35mm-format cameras.Notes on use When you carry the camera with the lens attached, make sure to hold both the
camera and the lens steadily.
Do not hold by any part of the lens that protrudes when focusing.
Precautions for flash use When using a built-in camera flash, make sure to shoot from at least 1m (3.3
feet) away from your subject. With certain of lens/flash combinations, the lens
may partially block the light of the flash, resulting in a shadow at the bottom of
the picture.
Vignetting When you use lens, the corners of the screen become darker than the center. To
reduce this phenomena (called vignetting), close the aperture by 1 to 2 stops.

cap. You can attach/detach the front lens cap in two ways, (1) and (2).
2 Align the orange index on the lens barrel with the orange
index on the camera (mounting index), then insert the lens into the camera mount and rotate it clockwise until it locks. Do not press the lens release button on the camera when mounting the lens.
Do not mount the lens at an angle.
To remove the lens (See illustration –.)While pressing and holding the lens release button on the camera, rotate the lens counterclockwise until it stops, then detach the lens. FocusingWhen using auto focus, the camera adjusts the focus automatically. While the camera is focusing automatically, do not touch the rotating focusing
ring.
The camera’s direct manual focus function cannot be used with this lens. (Some
cameras do not have the direct manual focus function. If your camera has this
function, this restriction is explained in the section on focusing, in your camera’s
instruction manual).
You cannot switch between AF/MF mode with the AF/MF button on the camera
(Depending on the camera, the AF/MF button may not exist. If your camera
has this function, this restriction is explained in the section on focusing, in your
camera’s instruction manual).
In MF (Manual Focus) mode, rotate the focusing ring while looking through the viewfinder to focus. (See illustration .) The focus signal in the viewfinder indicates the current degree of focusing.
To switch AF (Auto Focus)/MF (Manual Focus) modeYou can switch between AF (automatic focus) and MF (manual focus) with the focusing mode switch on the lens. Make sure to set the focusing mode switch (lever) on the camera to AF. Make sure to set the focusing mode switch to MF for manual focus. Do not
rotate the focusing ring without setting to MF. Rotating the focusing ring
forcibly without switching to MF may damage the focusing ring.
To shoot a subject at infinite distance in MF modeThe infinity position provides for some adjustment to compensate for focus shift caused by change in temperature. To shoot a subject at infinite distance in MF mode, use the viewfinder and set focus.4-149-563-01(1)©2009 Sony CorporationPrinted in JapanSAL50F18/ Lens for Digital Single Lens Reflex Camera/Objectif pour appareil photo numérique reflex à objectifs interchangeables/ DT 50mm F1.8 SAM

*1 35mm APS-C*2 ADI ADI
DT 50mm F1.8 SAM (1) (1) 1*1 The values for equivalent 35mm-format focal length and angle of view are based on Digital Single Lens Reflex Cameras equipped with an APS-C sized image sensor.
*2 Minimum focus is the shortest distance from the image sensor to the subject.
This lens is equipped with a distance encoder. The distance encoder allows more accurate measurement (ADI) by using a flash for ADI.
Depending on the lens mechanism, the focal length may change with any change of the shooting distance. The focal length assumes the lens is focused at infinity.
